一系列四个实验评估了兔的眼皮条件作用，在这种情况下，无条件刺激(US)可以不同地被假设为在呈现时与条件刺激(CS)配对时预先呈现(启动)在短期记忆中。在受试者之间和受试者内部的比较中，在CS-US配对之前不久进行美国陈述的结果比没有美国陈述的结果要少。预审启动US的递减效应依赖于这种US与随后的CS-US配对中包括的条件US的相似性，并且可以通过在启动US和CS-US配对之间插入分心刺激来消除。最后，如果弱启动US在条件化US之前，但在CS之后，即在CS-US间隔内，也观察到类似的条件反射减少。数据的总体模式支持瓦格纳的观点，即当刺激进入短期记忆时，它们通常会变得不那么有效。
A series of four experiments evaluated eyelid conditioning in the rabbit under circumstances in which the unconditioned stimulus (US) could variously be assumed to be prerepresented (primed) in short-term memory at the time of its presentation in pairing with a conditioned stimulus (CS). In both between- and within-subjects comparisons, less conditioning resulted when CS-US pairings were shortly preceded by US presentations than when not. The decremental effect of the pretrial priming US depended upon the similarity of such US to the subsequent conditioning US included in the CS-US pairing and could be removed by the interpolation of a distractor stimulus between the priming US and the CS-US pair. Finally, a similar decrement in conditioning was observed if a weak priming US was administered prior to the conditioning US but after the CS, that is, within the CS-US interval. The overall pattern of data supports Wagner's thesis that stimuli are rendered generally less effective when they are primed in short-term memory.
